Getting
introduced to the Usher
When I first joined the staff at Stereo Times,
one of the first manufacturer's reps I was
introduced to was Stan Tracht of Dallas,
Texas-based Thee High End. I found Stan to be
very affable, helpful and knowledgeable about
audio equipment in particular and the high-end
industry as a whole. He spoke highly of the
Usher Audio loudspeaker line and with good
reason. Not only are they extremely attractive
and exceedingly well built but they sound
fantastic too. Simply put, they represent one
of the very best values in home audio.
I met the speaker’s designer Mr. Tsai
Lien-Shui at the 2004 Winter CES in Las Vegas.
It was interesting to see how Mr. Tsai’s
fellow countrymen would come in to the Usher
room to pay there respect to him and
congratulate him on a job well done. You would
have thought he was just given a lifetime
achievement award and entrance into the
audiophile “Hall of Fame”. I got the distinct
impression that if his work got this type of
response from so many people that he must be
doing something special. So I just had to get
a pair of his speakers into my house to hear
what everyone else was hearing. Weeks later, I
finally got the Usher 6371s in for a review. I
was not disappointed. The 6371s are part of
Usher’s new “Six Series” loudspeaker line.
I first heard Usher speakers over at Dave
Thomas’ house when he was doing a review on
the splendid Usher AC-10s and was very
impressed with what I heard. When the 6371s
arrived, I opened the box and was stunned at
what I saw. I had seen these speakers at CES
but they were sitting on the side amongst a
row of other Usher speakers and were not being
played. But now here was this simply beautiful
speaker sitting in my room. It has a high-tech
looking silver gloss finish with real birch
side panels. I’m thinking to myself, “These
speakers have got to retail for about $9,000,
but knowing what I do about Usher, they’ll
probably go for about $6,000.” Silly me.
That’s just how impressive these speakers
look. I’m sure that if someone were anal
enough, they may be able to find some little
flaw to nit-pick about this speaker’s fit and
finish (I could not), but to us regular
fellows, the 6371 will easily be one of the
most beautiful and elegant looking pieces of
audio gear to enter your home. It wasn’t until
I was already more than a month into the
review process before I asked Stan how much
the speakers cost. When he told me they were
only $3,000, I was just dumbstruck. In the
weeks to follow, whenever I would have a
listening session, I would ask my friends to
guess the price of the speakers. I routinely
got responses in the $5-8,000 range except for
my sister-in-law Peggy who guessed $800. Bear
in mind that Peggy saw the fabulous $350,000
Maybach 62 at the 2004 Chicago Auto Show and
thought it cost around $60,000. To me, that
says a lot about the value and performance of
the Usher and very little about Peggy’s
ability to recognize quality.
Delivering the Ushers
The 6371s come in 3 boxes: One box for each
speaker and a smaller, heavy box for the
stands. The stands feel like cast iron and
must be affixed to the bottom of the speakers
with long, heavy-duty screws. Getting the
speakers out of the box was easy but mounting
the speakers on to these stands was a bit
tricky. Care should be taken during this
procedure so as to not damage the tweeter
housing that is made of the same walnut as the
side panels but is located on the top of the
speaker. Stan Tracht told me a couple of good
ways to do this but I figured out another way
own my own. [Author’s note: I am trusting
everyone who reads this review not to tell my
wife how I accomplished this, otherwise, I’m
sunk.] What I did was take a thick, soft
cushion off of the couch, set it on the floor
and then turned the speaker upside and rested
the top of the speaker on the cushion. I’m
sure not all of you can get away with this act
of war without being noticed like I did, and
will have to depend upon your skills of
negotiation to use other household artifacts
to accomplish the job. Good luck gentlemen.
Oh, I almost forgot. When mounting the stand
to the speaker, the end with the large
rectangle goes towards the rear of the
speaker. I had this backwards and felt very
inadequate when I stood the speakers back up,
only to find that I had mounted the stands
backwards. I also recommend using a powered
screwdriver because the screws that mount the
stand to the speaker are long. There are also
four spiked bolts per speaker and you’ll need
all of the strength in your wrist to screw the
spikes into the stands. These spikes are
large, solid, have a very confidence-inspiring
feel to them and are only to be used for
carpeted floors. As a nice touch Usher also
supplies a second set of spikes made of
plastic that are to be used on wooden floors.
These speakers are truly a physicist’s delight
because they can sit on the floor without
being mounted to the stands even though the
top of the speaker slopes back from the bottom
at about a five-degree angle. This is a very
cool look.
On
the front of the speaker, beneath the
top-mounted tweeter, are two 7” woofers that
cover the midrange and bass frequencies. A
gray grill cloth covers the drivers and also
adds to the attractiveness of this package. On
the back of the speakers is a 4” port you can
use to further affect the bass response of the
speakers in your room. There are two sets of
binding posts towards the bottom of the
speaker for bi-wiring. This brings me to my
only real caveat with the speaker. The
connectors are recessed into an opening that
does not allow for the use of speaker cables
that use large spades without getting cramped
in that confined space. It’s not so bad if you
want to use jumpers and or banana plugs for
your second set of speaker cables if you’re
bi-wiring, but can get tight if you use
spades.
One other item I need to mention about the
speakers is that there is a compartment on the
back of the speakers, below the connectors,
where you can add sand or leadshot to load the
speaker’s bass performance to the room. Now I
must confess that I didn’t take advantage of
this compartment, even though Stan Tracht
urged me to. One reason was because I got good
bass response from these speakers in whichever
location I had them in my room. NO, it wasn’t
quite room-shuddering bass. The bass was
always tight and tuneful and had enough warmth
to it to make you feel that it was there. The
other reason was because the audio policewoman
(a.k.a. wife) that I live with caught me
bringing leadshot into the house and asked me
what I was planning to do with it. When I
explained what I was going to do with it in
relation to the bass performance of the
speakers, she pointed out my penchant for
making messes and mentioned something about
not wanting to find any leadshot on her nice
carpet. I considered her words, carefully, and
formed a response to her in kind. But once I
considered the price to be paid in loss of
life and property value, I decided to hold
back my smart tongue and relented. Sorry about
that Stan.
To get into the technical aspects of the
6371’s I contacted the legendary Joe
D’Appolito, Usher’s design consultant: “The
design goals for the CP6371 were flat on-axis
response and broad uniform horizontal polar
response. The first goal yields accurate first
arrival information critical to imaging. The
second goal assures a balanced reverberant
field and broadens the sweet spot. This is
required because we judge overall frequency
balance psycho-acoustically by fusing (i.e.,
integrating) direct and reflected arrivals
over a period of 5-30 milliseconds (the Haas
fusion zone). To this end, the CP6371 is a two
and one-half way (2.5-way) system. The lower
woofer crosses out at 350Hz to prevent combing
response errors in the vertical plane. It
doubles the low-bass output and compensates
for the spreading loss.
The overall woofer pair/tweeter
crossover is an acoustic 4th-order in-phase
linkwitz alignment at 2450Hz. The crossover
uses heavy gauge air core coils and quality
film capacitors mounted on glass fiber
reinforced printed circuit boards.
All the drivers used in the CP6371 (and
all the Series 6 speakers) have been designed
by Mr. Tsai and are manufactured in-house by
Usher. Here are some details on the drivers:
Two 8945A woofers are used in the CP6371. The
8945A woofer is a very sophisticated
low-distortion woofer. It comprises a cast
aluminum frame and a carbon fiber filled paper
cone, a T-shaped pole piece with copper
shorting ring and copper sleeve Low-loss
linear suspension with a large flat spider and
large half-roll surround. The sophisticated
motor yields very low distortion at high SPLs.
The T9950 is a very low-distortion tweeter
with a 28mm coated silk dome, an aluminum
voice coil former, optimized pole piece
geometry, large rear chamber for low resonance
and light ferro-fluid damping. Internal wiring
is four 9s OFC and the connectors are by
Faston.”
The design of all Usher loudspeakers is a
joint effort between Mr. Lien-Shui Tsai,
President of Usher Audio Technologies, and Mr.
D’Appolito, who consults with Mr. Tsai on the
models to be produced. Mr. Tsai then decides
on the model details, including the driver
selection and enclosure design and cosmetics.
Mr. D’Apploito is responsible for the
crossover design and final voicing of the
system.
The Ushers deliver
I set the 6371s up in my listening room and
experimented with different locations. I
settled in on the speakers being six feet from
the rear wall and four feet from the
sidewalls, eight feet apart. I broke the
speakers in for about a week before I did any
serious listening to them. When I finally did
begin to listen to them, the first thing I
thought was speed. These speakers are fast. I
called Dave and asked him if he had the same
impression that I had in terms how fast the
speakers sounded and he concurred. I listen to
electrostatics, mostly, and had to ask myself
if I had been wrong all this time. The
generally held notion is that electrostatic
speakers are faster than dynamic driver
speakers. I do have to admit, compared to my
Martin-Logan Quests, the transition from the
highs to the midrange is not quite as seamless
but it was something I hardly noticed. The
speakers throw a wide, deep stage with good
stage height. I got the distinct impression
that I could walk up to performers and get the
sensation that they were in their own space.
On Mark O’Connor’s “Appalachian Journey” [Sony
Classical SK66782],
you can easily hear O’Connor’s violin spread
across the stage along with cellist Yo-Yo Ma
and bassist Edgar Meyer. Another area of the
speaker’s performance I feel compelled to
share with you is that the speakers are a
little on the forward sounding side. The
electronics and cables you use will greatly
effect this. With the Dynamic Design White and
Platinum series of cables, which I consider to
be very neutral, the forwardness was quite
clear. When using Roger Tiller’s wonderful
sounding Blue Marble Audio cables and the
equally as good sounding Virtual Dynamic Nite
cables, the sound was not as forward. I did
not find this objectionable at all. Of all of
my fellow audiophile buddies who came by and
listened, only one did not like the
forwardness of the speakers. Most didn’t feel
that it mattered and several commented that
this is the way they like their music
portrayed. I only mention this become some
readers really get into how forward sounding
or how far back a speaker’s image is. I feel
that this is cable dependent and recommend
anyone considering buying this speaker to try
different cables. I’m sure you’ll find a cable
that will dial your stage in just right for
your listening biases.
Another quality this speaker has is
musicality. That special little something that
makes you enjoy the musical experience to the
point of wanting to nod your head or tap your
toes along with the music. This added to my
enjoyment of listening to Sting’s “Nothing
Like The Sun” [CD 6402/DX 2163] where
The
Lazarus Heart and History Will Teach Us
Nothing had all the drive and head nodding you
could want. Listening to Beethoven’s Symphony
#3 as performed by the New York Philharmonic
Orchestra and led by Zubin Mehta [CBS/Sony
38DC2], you could really get a sense of Avery
Fisher Hall, which is where this performance
took place. It was easy to clearly delineate
the different sections of the orchestra and
get a good feel for the layering. Going to the
opposite end of the spectrum, Luiz Bonfa’s
“Non-Stop to Brazil” [Chesky JD29], is more of
an intimate type of performance and he and his
mellow, romantic guitar playing felt like they
were in the room. On Fourplay’s new CD
“Journey” [Bluebird 82876-613582] I could
easily feel and follow Nathan East’s bass line
on Cool Train. Another example of the
6371s tuneful bass could be found on Buster
William’s “Tokudo” where he really gets into
the track entitled Fuego. Here,
Buster’s chord progressions and deft finger
work could really be appreciated on the
dynamic and lively sounding Ushers. Female
vocals are also rendered beautifully by the
6371s. My new favorite female vocalist, Jane
Monheit, has a fantastic CD out called “In The
Sun” [Warlock NC-4234-2] that is simply
enrapturing. I just love her voice, her style,
and her range. To me, her tone and her
phrasing are special. On the tracks, Once I
walked in the Sun which is a duet with
Ivan Lins, It Never Entered My Mind and
Haunted Heart, all of these qualities
are clearly displayed. She also has a light,
up tempo spin to Cheek to Cheek that I
enjoyed as well. The 6371 put her front and
center in my listening room as I know she was
putting on a performance just for me.
Winding it up
The only speaker I had on hand to compare the
6371s to were a pair of the classic Von
Schweikert VR-4.5s. The 4.5s have the Ushers
beat in the area that the VRs do best, bass.
Even though I didn’t mass load the speakers
with the leadshot, I don’t believe that the
two 7 inchers on the Ushers would best the two
9 inchers on the 4.5s. That being said, the
6371s, over all, were faster, more detailed,
and had better focus while the 4.5s had a
small edge with a wider and deeper stage. With
the speed, detail, focus and overall
musicality of the 6371s, I would give it the
edge over my venerable 4.5s. What would be an
even more interesting comparison would be the
Von Schweikert VR-4jrs with the Usher
speakers. Amplifier wise, the 6371s sounded
really good with the Electrocompaniet AW-220s
but I had the most enjoyment with the Soaring
Audio SLC-A300 and the Conrad Johnson MF2500A
driving them. I enjoyed the speed and
transient response of the 6371/Soaring Audio
combination as well as the fuller, warmer bass
and a larger stage and with the level of
musicality that the speakers had with the
2500A. All in all, with awesome fit and
finish, excellent musical performance, and a
real-world price, you get an extremely good
value for your money. It’s not hard at all to
give these speakers a very high
recommendation.
